Areas of Research on Natural Language
Early cognitive developments in humans and their analogs in Artificial Intelligence, including work conducted within the EU Integrated Project ITalk: "Integration and Transfer of Action and Language in Robots" funded by the European Commission under contract number FP7-214668.
The evolution of linguistic communication. This includes investigating the emergence of grammar in human language, using Information Theory techniques to find methods of coding language that make communication more efficient. See an overview of Emergence of Communication and Language
Development of first Ferret software system, for detection of similar text in large document collections, and the display of similar passages side by side.
Transfer of language processing techniques between English and Chinese, and their extension. This has primarily been undertaken by Dr JunPeng Bao, Royal Society International Fellow at the University of Hertfordshire from Xi'an Jiaotong University from April 2006 to April 2007.
Using the pattern matching powers of neural networks to detect syntactic patterns in language. The prototype ALPINE neural parser will find the subject,and head of the subject, of each sentence.
Development of real time subtitles for live TV programmes, using speech recognition technology. Used for BBC2 sports programmes.
